lie it kuown,that i. uors'rus l". limsixo, a eitixen of the i'nited States, residing at Denver, in the count,v otA Denver and iS'tate ot' Coloradtnhave invented certain new and useful improvements in tar Brakes` oi' which the following is a speeltr cation.

.\l v intention relates to an apparatus i'or operating the brakesoi' a railwa)r ear. and pertains more partieularly to a manuali)Y op` erated apparatus t'or setting and releasing railwa v ear brakes, more espeeiall)v the brakes oi' a. freight car. The great increase in weight. and eapaeitv of modern freight ears makes it ver)v ditiieult. with the old type ot" hand brake mechanism` to reliably eoutrol the ear in switeliing, for example` by manual operation. Railway freight ears are o rdinarilv at theI present time providedl with a brake stati' around whieh a ehain is wound when the brakes are set, the stati being pro `vided with a hand wheel and with a loot operated ratchet meehanislu for holding the brakes'in the set position. 'l`he operation ot' this meehanism is slow, requires ver v eon siderahle exertion on the part ol' the brakeman. and is attended with great danger. The brakeman ol'ten uses a wooden pole or elub whirh engages with the spokes of the hand wheel to augment the leverage. lflven so. it frequently happens that the brakes cannot be set with sullieient power to prebe dangerous to the brakeman and damaging to the ear and its eargo. trulyy on the end ot' the stati' and as a result the brakenian may believe the when sueh is not the. ease. brakes the holding dog is kieked out from the ratehet. 'l`he release produres a ver v quiek and violent reaetion likel'v to eause the brakeman to lose his balanee ii' he has his `hands on the wheel. These imperleetions in the type oi' apparatus almost universall` used at the present time in. this country for Vthe manual operation of freight ear brakes have heen theeause of eonsiderable loss oi' life and injurv to trainmen besides bringing about dete''ioration and damage to rollln releasing the Specification of Letters Patent.

rl`he principal object ofthe present invention is to provide a manually operable brake meehanism which can be, operated very qnieklv and eertainl v, whieh is rap-able of pressing the, brake shoes against the wheels with very great force, and whieh ean be operated with relatively small exertion on the part oi' the brakeinan'through movements ol' a lever operated lrv one hand. this latter feature enabling the brakeman to steadiv himself with the other hand b v hold ing onto the ear.

`further objet-tof the invention is to provide a manually operated ear braking ap paratus whieh will be relatively simple in its eonstruetion. positive in its operation. strong., durable` and of sueh eompaetness o1l strueture that it ean be plaeed on the railway freight ear without interferenee with other apparatuses the ear. and without undue protrusion ot parts ol' the mechanism from the ear body.

'Referring lirst 4to Figs.1 to 8 inclusive, A desi nates one side of a railway car to which the gb'rake mechanism of my invention is applied. -1t will be understood that the invention is not to be considered as limited to use on a gondola car or to the application of the working parts to the. side of the car. With modifications which will be obvious to those skilled in this art, the mechanism can be readily adapted for installation upon either the ends or sidesof box cars or upon other types of railway cars.

In thc preferred embodiment of the inven- V tion disclosed in the drawings, 1 designates a. housing 'provided with lugsu adapted to be secured to the body of the` car by bolts 4. The housing is formed with an internal rack 6 0n one side thereof. and in order to reduce friction it may be provided at its opposite side with a ball race 7 in which are arranged-a series of antifriction balls'9 against which bears a movable rack basil. 14 designates a pinion adapted to mesh with,

the stationaryv rack 6 and the movable rack a bar 11. The pinion is mounted on the square end 15 of a hub extension formed upon a `hand lever 17. this lever being .composed preferably of a lower member 18 and a handle member 19. The pinion is held upon the lever bye bolt 21 and washer 22. The hub on the lever is formed withv a cylil'ldrical ortion 15'* revolubly and slidably mounted 1n a slot 16'in one side of housing A, the washer being slidalily Inounlted in a corresponding'slot 16a in the corresponding side of the housin The handle member 19 of the lever is sliably connected with'the lower lever member 18 by a loop 24 `formed on the latter. Studs 25 on the lower end of the handle menber limit the outward movement of the latter. t Cdesignates a chain or other tension member disposed under the car bodyend forming a part of the rigging employed for setting the brake shoes against the wheels of the car. Movement is transmitted to the moved to set the brakes.

tension member (l froin the movable element 11 of the power applying device just described by means of a rocking and rolling transmission element 34 which functions through its rocking movement to cha-nge the vertical pull on the member 11 to a horizontal pull on the member and by its movement translation, that is` the linear movement of its fulcrum, to increase the capaity of the apparatus for taking up slack 1n the brake connections over that whichl said apparatus would have if the transmission device rocked on a vfixed pivot. The rocking transmission element 34 is associated with a supporting member 27 which, in the embodr ment of the invention shown inthe drawings, is formed integral with the housin 1. This supporting member is formed wit i preferably incllned rack .37. the inclination of which is in the direction downwardl1 away from the brake chain C, with which. engages a spur gear B5 formed at the juno-- tion ot' the two arms 38. 39 of the trans mission device which is in the form of a bell crank. The supporting device 27 is provided with a pair of spaced, depending, guiding flanges 28 formed with internal channels 3U. having the inclination of rack 3T. into which project studs 32 formed on the bell crank 34. The brake operating chain. or other element employed 1n placeA thereof, is secured to the arm 39 of the bell crank. Theotlrer arm 38 of the bell crank is connected by link 4U with the rack bar 1l, the latter being formed for this purpose with a lug 41 which perforated as shown 111542. o-

The detent device is provided for holding the rack bar in the position to which it is In the embodiment ot' the invention shown in the drawings, the upper end of thc lug 41 on rack bar 11 is in the form of a clevis 4b to which is pivoted, by means of a pin 4H, the detcnt or pawl 49 'adapted to engage with the toothed holdiltg or ratchet bar 51 within the housing The lug 41 projects upwardly beyond the pivot 48 and has pivoted to its upper end a weighted tripping member 53 which normally servus to hold the awl in engagement with ratchet bar 51. lior release of the brakes the tripping device is turned from the position shown in Fig. 2 to that shown in Fig. 4. ln the latter position it tends to throw and hold the pawl 49 out of engagement with the ratchet barl and against a stop shoulder 52 formed on ,lug 41. 56 is a stud which projects from rack bar 51' into the path of the tripping devitie 53 when the latter is in the releasing position, shown in Fig. 4. The stud 56 is so placed as to throw the tripping dvicefrom the position shown in Fig. 4 to its original position (Fig. 2) when the rack bar on release of the blakes approaches the lower limit ,of its downward movement. This re-sets the pawl against the rack bar l so that it is in readiness to hold the saine against downward movement at the next setting operation of the brakes.

In the modilieation shown in Figs. 9 and ttl. the apparatus is constructed precisely as that just described. except for a change in the torni of the transmission element. [n these two ligures the correswnding parts of the apparatus are given reference numerals corrcspoiuling to the reference numerals used in the first eight figures but with the.V distinguishing exponent "i ln the modilied tonstrnction the arm of the transmission device or bell crank 34 is formed with a rounded winding surface .3T and the brake operating chain is attached to the, bell lcrank so that when the latter is rocked the chain is brought to bear for a portion of its length against the surface 5T. As a result there is no loss of take-up on the chain due to the angular movement of the. hell crank but, on the contrary. bv giving the surface 5T proper configuration the rocking of the bell crank may involve additional take-up on the chain.

Summa/'y of operation-'To set the brakes the trainman` alter extending the collapsible level' pulls the lever to or toward the. position shown in dotted lines in l"ig. l. lt will be understood that the slack in the brake connections will dittei/- for dillerent cars. and for the same installation 4as the brake shoes and other parts of the brake mechanism wear. so that the extent to which the lever must be rocked will varv. rl`he first movement ot the lever takes up the slack of the brake connections. lts continued movement creates braking pressure between the brake shoes and wheels of the. wir. 'l`he apparatus xnav be operati-d with one hand. Due to the peculiar construction otv the rocking and rolling transmission device` the take-up on the brake connections will he rapid and. when necessary. the amplitude of movement ol4 the parts will be considerable without the necessity ol' Inaking the transmission device ol' anA inconvenient size. rl`lnI hralics are held set h v engagement oll pa wl l!) with the ratchet bar 5l. 'l`o reeasc the brake.`4 the trainman tnoves the tripping device :Til from the position shown in Fig. 2 to that shown in Fig. 4. v pressing lou n on the operating lever l? sullicicntlv to relieve thtl pressure between the pawl and tlre ratchet bar the pawl will be thrown out ol' engagement with the rati het bac o that the operating lever and thil olla-r parts of the apparatus may he allowed to return to their normal positions ol' eh-asc. 'lhe downward movement of tlu` rat-l. bar ll brings the tripping device ."i imo contact with the stud 5t). 'l`his reverses tin position of the trippingr device and throws the pawl 4t) into contact with the ratchet bar in readiness to hold the brakes set on the nextl operation o t' the apparatus.
